So I'd say that authorities believe that tourism in the area will heavily increase in the short term or they wouldn't be investing so much money to increase transport capacity
Barcelona can't keep up with the tourism demands, and visitors have already started displacing the local population.
The plan is to create a secondary touristic hub in Tarragona to absorb the tourists Barcelona can't handle. Reus airport is set to become Barcelona's second international airport, much like Paris' Orly or London's Stansted. It will be linked to Madrid and Barcelona via high speed trains. Madrid is currently just two and a half hours away, and Barcelona 35 minutes.
Even then, Southern Europe's most important transportation axis, the Mediterranean Corridor, passes right by the resort.
The area Universal Mediterranea was in was specifically developed for EuroDisneyland. Even the district of Salou (where the resort is) was created for Disney, to serve the same purpose as Reedy Creek Development district in WDW.
After doing some research, it was revealed that Salou was to be EuroDisneyland's home up until the very end of the process. However, Michael Eisner and Frank Wells ultimately decided to settle in France.
Costa Daurada was built to accomodate such resort, and Universal Mediterranea would have succeeded if it wasn't for the company wide crisis. Even them, the resort has always managed to be profitable, while Disneyland Paris still struggled to break even.
Every new development between the 2004-2023 period can be traced back to the plans Universal had for the resorts (even Ferrari Land, though that's quite a different story).
Many Universal projects were directly inspired by or considered for Port Aventura. Islands of Adventure, the Universal Monsters land in Epic Universe, Volcano Bay...
Everything is still there.
The hotels are almost always at capacity, the resort is Spain's second most visited attraction (right after Sagrada Familia) and it is constantly breaking both profit and attendance records.
